Question Answer
mid-Ocean Ridge a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading. An example is the Mid-Atlantic Ridge
continental shelf the area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean. The continental shelf is geologically part of the continental crust.
Abyssal Plain An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
Trench a long, narrow excavation in the ground, the earth from which is thrown up in front to serve as a shelter from enemy fire or attack
Continental Slop The sloping region between a continental shelf and a continental rise. A continental slope is typically about 20 km (12.4 mi) wide, consists of muds and silts, and is often crosscut by submarine canyons.
Seamount An underwater mountain rising from the ocean floor and having a peaked or flat- topped summit below the surface of the sea.
Continental Rise The continental rise is an underwater feature found between the continental slope and the abyssal plain. This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean
Submarine Canyon A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km, from canyon floor to canyon rim, as with the Great Bahama Canyon.
